Text character interception method, text character interception device and storage medium

The invention relates to a text character interception method, a text character interception device and a storage medium, in particular to the technical field of computers, and can be applied to the field of financial science and technology. The method comprises the following steps: acquiring a target text character; based on byte positions of to-be-intercepted characters in the target text characters in the original text characters, determining a position relation model of the to-be-intercepted characters between the target text characters and the original text characters; performing loop solving on the position relation model based on a median algorithm, determining an interception position of the to-be-intercepted character in the target text character, and intercepting the to-be-intercepted character from the target text character based on the interception position; the interception position is used for representing an initial interception byte and a byte interception length of the character to be interce
